Instant shipping restriction decisions with flat pricing. Check ZIP codes and products in real time without slowing checkout, in the cloud or self-hosted.
Built for modern commerce and platform teams, RestrIQ delivers predictable performance, clear decisions, and full control over where the system runs — across a wide range of products with state and local shipping rules.
Covering all U.S. states with ZIP-level granularity where city or county rules differ from state law, the more specific rule automatically applies.
Shipping restrictions built for modern commerce
Most shipping restriction systems weren’t built for today’s traffic, scale, or regulatory expectations. They introduce latency at checkout, unpredictable usage-based pricing, and unnecessary exposure of customer data. RestrIQ removes latency, pricing uncertainty, and privacy risk—without sacrificing precision or control.
Lightning-fast
RestrIQ shipping decisions are instant — completing in fractions of a second — so they don’t slow checkout or increase abandonment.
A cart with 100 products resolves in microseconds. Compliance never becomes the bottleneck, regardless of cart size.
Decision logic completes in ~100µs—about the time it takes lightning to cross a football field. Load-balanced, multi-region cloud responses under 100ms; self-hosted deployments under ~5ms end-to-end.
Predictable pricing
Growth shouldn’t introduce billing anxiety.
RestrIQ offers flat-rate pricing with no per-shipment or per-decision metering so costs stay stable even during promotions and peak traffic. There are no per-request fees or usage-based charges
Self-host when you need full control
Self-host to keep requests inside your environment and achieve near-instant responses.
RestrIQ is well suited for SaaS platforms and service providers including e-commerce, ERP, and order-fulfillment systems that need predictable latency, tenant isolation, and tight integration with their existing infrastructure.
RestrIQ has no external dependencies — no database, no third-party API calls, no background services.
Privacy by design
RestrIQ is designed to make shipping decisions without collecting or retaining personal consumer data.
Requests contain only the minimum information required to determine eligibility, and no user profiles, behavioral data, or transaction histories are stored.
How it works
Send RestrIQ a ZIP code and product identifiers, get an immediate decision. Run it in our cloud for a fully managed experience, or deploy it in your own environment for maximum control and minimal latency.
When an item can't ship, you get the reason why and suggested modifications to make it compliant — so you can
convert blocked sales into completed orders instead of dead ends.
Control what happens when a product isn't in the database — block by default for safety, or allow unknown items through with a single request parameter.
Clear responses,
no ambiguity
Every request to RestrIQ returns a simple result:
shippable: true | false
With a per-UPC breakdown explaining each decision—ready for checkout or fulfillment logic.
